Patent: Canon EF 600mm f/4 DO IS

[Canon Rumors]

A patent for the Canon EF 600mm f/4 DO IS has finally appeared. A <a href="http://www.canonrumors.com/canon-ef-600mm-f4-do-br-at-canon-expo/">prototype of this lens was shown in September of 2015</a> at the Canon EXPO. We <a href="http://www.canonrumors.com/canon-ef-600mm-f4-do-is-to-arrive-in-late-2017-cr2/">were also told a few months ago</a> that the retail version of this lens could be coming near the end of 2017, though we haven’t received confirmation.</p>
<p>Patent publication number 2016-200685 (Google Translated)</p>
<ul>
<li>Release date 2016.12.1</li>
<li>Application date 2015.4.9</li>
<li>Focal length 585.00</li>
<li>F number 4.12</li>
<li>Half angle of view (degree) 2.12</li>
<li>Image height 21.64</li>
<li>Lens total length 335.32</li>
<li>BF 66.92</li>
</ul>
<p>We hope to hear confirmation of a release date in the coming months. We’d also like to see a price tag, but that’s far less likely this far out from an announcement.</p>

I am so looking forward to trying this lens out, but might have to sell everything I own to be able to own it though

 

[Maximilian]

It will be interesting to see, how much weight they can save compared to the 600/4L II.
Also the optical performance will be interesting, given from what we could see from the 400/4 DO II.

 

[BeenThere]

Are we ready for a $15,000 - $16,000 lens?

It'll be a tough call between buying a car or a lens

What I would love to see is a built-in extender like the one on the 200-400/1.4x. I doubt the extra price will make a big difference to those who can afford the lens.

Depends on how good it will be optically. What if it won't match the non-DO IQ? Is it a direct replacement or a separate product? Let's wait and see...

 

[compupix]

You should have made the red line green. Canon's DO lenses have a green line.

 

[tron]

Yeeeeeeeeeeees! Finally there is hope for such a lens!
Nooooooooooooooooooo! I will not be able to afford it!

 

[NancyP]

Heck, I usually get about 18 years out of a car. The current car is still a baby. Maybe I will look longingly at this. Could I lift it?

If I recall correctly you have (or mentioned you were thinking about getting) a 500mm f/4L IS II. It weighs 3.2 Kg and the prototype had about the same weight (and it was 7cm shorter...).

Yeah, when I go out shooting birds the value of the gear in the car (1D X, 600/4L IS II, RRS tripod+monopod) exceeds the value of the car.

+1 on the built-in extender, I use my 600/4 with a 1.4x much of the time.

 

[vscd]

Do I want it? No! Do I need it? No! Do I want to try it out for a day? HELL YEAH!!!!!

 

[Alex_M]

I would argue that such a lens priced at $16,000 would hold it's value better than a car priced similarly.
In fact, I would even expect the price for such a lens to go only up due to hidden material, labour and manufacturing cost inflation, taxes and duties. If only the Canon EF mount is still around in 5-10 years time from now.

We've been there for quite a while........

[fegari]

Based on the patent's description of the lens length, the lenght is virtually identical to the 400 2.8 II or 200-400 F4. The diameter I guess will also be in between those two, I'd say closer to the 400 2.8's diameter. The weight I guess much closer to the 500 II, the lightest of all those.

A patent for the Canon EF 600mm f/4 DO IS has finally appeared.

First DO lens I would have any interest in. Like to see it going on sale, a price tag and some (impressive) test shots to prove itself a worthy acquisition.

 

[Loswr]

Based on the patent's description of the lens length, the lenght is virtually identical to the 400 2.8 II or 200-400 F4.

Not quite. Those are 343mm (13.5") and 366mm (14.4"), respectively, whereas the physical length of this patented lens would be ~292mm (11.5"). A 50mm / 2" / 15% length reduction is not insignificant.

Keep in mind that a 'lens patent' is really an optical formula patent, so the 'lens total length' is from the front element to the sensor. To compare with measurements of actual lenses, you need to subtract the 43mm flange focal distance from the patented length.

Yeah, when I go out shooting birds the value of the gear in the car (1D X, 600/4L IS II, RRS tripod+monopod) exceeds the value of the car.

When I go out shooting with my EOS M3 and a couple of EF-M lenses the value of that gear exceeds the value of the car!

When I cycled to the lab this morning, the Black Rapid strap alone exceeded the value of my bike.
